` AUTOMATIC Winnovv venrinnfronf i Application:filed .Tune 26,

The present invention'relates to automatic Window ventilators and is `more particularly directed to an improvement uponthe strucl tureillustrated in thepatent to Daniel J. De

Grasse, No. 1,651,259, and *issuedv November" 29,1927. inthe said De Grasse patent, an

automatic Window ventilator lis disclosed oi a character adapted to be associated with the lovver edge of the lower sash and `,entend downwardly over the step of the Window sill so that rain cannot. beat into the Window under the edge of theventilator as is generallyfthe case in other" of yentilator.V

vWhen the Window `is closed, hovvever, the

, lower edge of the lower sash engagesa trigger Whi'chcauses the ventilator to be elevated into a position wher-ein its lovveredge is alcove the step ofthe sill so that upon continued lowering of the sash, the sash is adapted to act upon cani like surfaces lWith `which the deflector is provided lorthe `purpose of springing the detlectorout ofthe path oit the sash to permit the sashtobe fully closed.` p y 4 The structuredisclosed in the De vGrrasse patent is a practical` and etlicient one,`lout experience in the manufacture of these ven-` tilators has convinced me that they can be more economically"constructed and can be so organized `as to operate more smoothly and eficientl in `the performance of their Euncf ence the present invention.

tions. y In the De Grasse structure, ari-important element resides in the movement of a link associated With the trigger `and loy virtue of i which link the ventilator-is raised and loW-.

. `tends `for `the greater portion ofthe heightof ered and supported for swinging movement.

The linli of the patent is pivoted directly to the frame Orcasementojf the ivindoyvfand eX- the ventilator.

The two lateralhalves of the ventilator are identical except for the fact that they are made right and left and therefore the description of one lat-eral half will suiiice for both. Thus, referring to the drawings, 6

' designates a mounting strip or plate. This strip is of metal and is of a height slightly in l excess of the overall height of the ventilator triangular contour and is provided at its inner edge with a right angieflange 11.` It

is further formed adJacent its lower end with an outward extension 12, the upright edge of which is curved as shown at 13. Also rigid witheach mounting strip` 6 is a headed stud 14 which extends through an angle slot 15.

One leo'v 16 of theangle slot 15 extends substantially horizontal while the other leg 17 extends substantially vertical.` The stud f passes through the slot 15`and also extends through a'slot 18 in the u per `end of aY link 19.' The head of thestuc 14 is sufficiently large to hold the link `19 and the plate closely to the mounting strip 6'.

` Rigid'ly mounted upon the plate 10 at some little distance Vbelow the slot is a` headed stud 2U which studforms a pivot for a trig-' ger 2`1t-o which the lower end of the link 19 is secured by a rivet 22. l

The trigger 21 is adapted for pivotal u1ovemeut about its pivot from one extreme position shown in Figure lto the other extreme position shown in Figure 2,'a stop 23 being provided 'to limit the latter position. When in such latter position, the lupper face of the trigger lies alongside of the edge'l. In orlder that such upperij'ace may be smooth and will not unduly wear the window sashby which itis adapted to be engaged, it is-pref- 'erably provided with a laterally extending 7 'lange24 which produces a flat broad surface Y for engagement with the sash.

"flpurpose of the air de l ventilatorand .is designated 26 in the draw-` ings.

lAt the extreme bottom of eachlplate 410 a socket lfis formed `by bending up "the plate as shown and these sockets ofbotli platesare adapted to c oiiperatel with the flanges 11 to l support aglass panel which extends transversely of the window Vand seats in said sockets and bears against'the flanges at its oppositefends. This `glass Vpanel serves the fleeting element of the Y To hold the upper portion of the panel in engagement with the flanges 11,1etainers 27 are provided. One of these retainers 27 is pivoted to each of the end plates l0 by means oi' a pivot 28 and the retainers are normally locked in a position tohold the glass in place by means of a pressed out boss 29 on the plate extending into a perforation 30 of the retainer. This arrangement forms a resilient lock which precludes inadvertent pivotal movement ofthe retainer.

The normal position of the parts is as shown in Figure 1 where the lower sash is shown as raised. Under this condition of things, the weight oit the glass panel and the end plates 10 cause the parts to gravitateinto a position wherein the lower edge of the panel will overlie the step or abutment 5 and preclude rain from beating in under `the ventilator on to the inner sill 3. The weight of all the movable parts is at this time carried by the studs 8 and 14. These studs enga Ging with the upper ends of the slots 9 ands 17. Vhenit is desired to close the window, the lowering of the sash 2 will cause the lower rail of the sash to engage with the' triggers 21, and as the sash continues to descend, each trigger will be swung downwardly. During this downward swinging movement of the trigger, it functions asalever having a ful crum 22 whicliis supported by the link 19 suspended from the stud 14. Thus, the down-` ward swinging of thetrigger brings about an upward movement oit its pivot `20which necessarily results in au elevation of the end plate 1() to which said pivot is rigidly secured so that by the time the sash has been lowered to the position shown in Fig. 2 to bring the trigger Vinto engagement with the stop 23, each side plate will have been elevated to the full line position Aoi Fig. 2 wherein its lower end will be above the surface of the `inner sill of the sash to permit the sash to be completely closed. l i Y During these operationsto which I have referred, the elevation of the plates under the action of theftrigger will. have caused the end plates to be guided by movement ofthe slot 17 with respect tothe stud 14 of each of them and afterv the side plates are partially elevated thehorizontal leg 15 of each `angle slot will coaot wi-ththe studi/l to furthereleva'te and guide the end plate in their swingingmove? weaves `ivlientlie sash is completely closed, the parts will partake ot' the `dotted linelfiositionoiA Figure 2 and will ren'iain in this position until the sash is again raisedwhereupon the operations described will be reversed under the force oi' gravity until the parts reassuine the relative positions shown in F ig. l.

With the arrangement which l have described, the operation is unusually smooth,A

since the tierces are applied in a moet etlieient manner to accon'iplisli` the work ttor which theyai'eintendeil l callparticular attention to the relatively short links 19, which, through their use, permit of a very compact and smoothly operating arrangementpractically devoidot lostinotion during opera- "tion:

ln the manufacture ot ventilators in ac eordai'ice with the present invention, the end plates l0, links l!) and triggers 2li, together with the studs, stops and pivots 3, lfl, 20, 22 and 23 are all assembled with respect to the inount'in' strips G which are made of such length and so proportioned that the incre piiisitioiiing of 'these mounting strips on a window traine with the lower end oit each" strip resting` on the sillS will, of itseljl, bring about a proper positioning of all the operating parts.i with r-espect to the window sash.

ln order to mount the ventilator on the window traine, it is therefore only necessary to bring the mounting strips into position and to insert the screw to secure the strips tothe frame. This work can be done by unskilled labor and greatly eizpedites and econoinizes in the installation ot the construction. Furtherinore, by mounting all the parts upon fairly heavy plates, adequate` anchorage for the vstuds is provided anda more rigid and durable construction results.

that the swinging movement ventilator is accomplished by engagementbetween the sash `and the trigger, but, it desired, the edges 13 oit the end plates may be shaped as to coincide with the upper faces ot the triggers, so `as to also be engaged by thesash when the triggers are against the stops 23, so that the swinging inoveinent of the ventilator is accomplished b i eneaeement oil; the sash diiectlY with the .l ci n .Y

edges 13.

lt will be apparent that the vei'itilator et this invention is entirely automatic and that the mere act of raising and lowering the Window sash brings, about movement oi the ventilater `from functioning to`non-functioning` position and vice versa. i 1
